Buy a can of octaroon.

The extra .99 is cus premium has more speed in it

My Clio 172 'requires' 98RON. I feed it 95 and it hasn't knocked once.

It could be worse. You could have to mix your own fuel.

Scotty wants you to stop being a fucking retard.

how much would it cost to fill up an R34 GT-R in USA?

wew maybe buy an ecobox next time bud.

Have you tried to buy gas in Brazil? R$4,02 regular

Such is life.

Do you not remember ten years ago when regular was over $4 a gallon? I was driving a Jeep Grand Cherokee and delivering Chinese food part time. If you want to talk about paying for fucking gas.....

>reveals himself to be an off-duty cop
Holy shit, I haven't laughed this much in a a long time

Thanks user

That's why they call then trannys

...

>buying anything but premium

Are you some sort of nigger?

why have they started doing this

literally 30 cent increments between the regular, mid, and premium, it used to be like 5 cents

went to get gas the other day and the billboard advertised only 2.10 regular and 2.40 for "plus" I was like wow that's cheap and so I pulled in and apparently 'plus' was the mid-grade and 'premium' was 2.70, so I pulled straight through and left those niggers, almost fooled me

do you guise even gasbuddy?

>mfw there's only one station in my city that doesn't have a ridiculous premium upcharge. everyone else is +$0.60 over regular

>spend $5 to drive across the city to save $2

Are octane enhancing additives and regular grade fuel a viable way to save money on premium gasoline or does the premium fuel inherently have something that can't be added?

Wait a second, are octane enhancing additives just ethanol?

>>>>>> when people complaint about gas prices in the states

Checks out

Using OP's example to prove your retarded ass wrong

>16 gallon tank

My motorbike knocks when working hard up hills on regular, but it doesn't seem to be causing any harm so don't really care.

One of the things I don't miss about my German car. Between 4$/gallon and expensive parts I don't know

Back when it was near $4-5 a gallon I could understand it but at $2.5 or less, it's cheap as fuck especially if you get anything over like 20MPG.

Go to a better gas station. Not all of them overcharge for premium.

>My Clio 172 'requires' 98RON. I feed it 95 and it hasn't knocked once.

You are confusing the disappearance of the knock sound as solving the problem. The disappearance of the sound only means the computer was able to MISadjust the engine to non-optimal inefficient settings in order to prevent the knock. It is recommended that you use the proper fuel so that the computer can adjust engine settings closer to optimal.

Your unasked question is "How much premium is needed to get to optimal for my engine's condition, deposits, and tolerances?" You can test it of course. You know how many gallons remain in the tank of 87 octane of Arco Regular. Note the mileage MPG you get on that gas. You can let it run to under a quarter and fill up with 89 octane of Arco and measure the MPG. When it drops to under a quarter tank, fill with 92 octane and check MPG. If the MPG improved over the 89, then you car wants more octane than 89 since the higher octane allowed the computer to adjust the settings closer to ideal.

Your best choice for higher octane is Top Tier gasoline. That's because the top tier standard specifies that it cannot have more than 10% ethanol. Since ethanol has higher octane than gas, non top tier gas might boost the octane with ethanol so that gas can have over 10% ethanol.

>get robbed by 2 helmeted men in a bike
>robbers shoot at cop who shoots back killing robbers
>cop gets hacked to death by a tribe of niggers

The USA cities sometimes have festivals where gasoline that day is free for everyone. It's a nationwide phenomenon that only places with Freedom! can enjoy.

could this have possibly be taken by a hwite man

>non top tier gas might boost the octane with ethanol so that gas can have over 10% ethanol.

I'm pretty sure they have to tell you that at the pump tho, and that it's a federal requirement that they do so, in the states at least. That's why all the pumps you see have stickers on them that say "may contain up to 10% ethanol". Higher blends = different stickers. If you can read, you should be fine.

that's cute, look at those youths having a good time with that abandoned Caprice.

I wish more police departments donated toys to the less fortunate.

>gas is $2.69/gal regular cash, $2.75/gal credit in my area of New York
>live near the border of Connecticut
>drive over to the Costco Gas station in Connecticut
>get premium for $2.59/gallon from costco (regular about 35 cents less than that)

35 cents a gallon times 15 gallons would mean you save like 5 bucks to completely fill your car. If you burn 1 there and back you're getting like a gallon and a half over what youd back in NYC.

I don't live in NYC, I live in Westchester on the border of Putnam county - substantially closer to connecticut than NYC(also gas in NYC is wayyyy more expensive than $2.69/gal). I make a bunch of other stops in the area (minimally Costco's own warehouse and Stew Leonard's) so I'm not driving there solely to fill my tank. I just try to time my larger fill-ups when I can to be when I make that circuit up in CT.

Maybe this one

What are the main additives used to add octane level to gasoline in order to make it "premium"? Is it toulene or naptha?

>are octane enhancing additives just ethanol?
No, there are many including methanol in the cheap dollar-store additives (fuel drier, octane booster, injector cleaner). Especially effective octane enhancers are metallic. There is methylcyclopentadienyl manganese tricarbonyl which uses manganese. There is tetraethyllead which uses lead. There is ferrocene (iron pentacarbonyl is obsolete) which uses iron. These three organo-metallics have toxic byproducts. Top Tier Gasoline sets a limit on metallic additives which means iso-octane and toulene remain as principal octane boosting agents.

If you have a source of pure toulene, you could presumably mix it with your 87 gasoline to have a higher octane. Toulene is rated AKI 114 octane. Gas stations such as Arco offer three grades at the pump: 87, 89, and 92. They basically mix the 87 and 92 together to get the 89. If 87 is $2.51, 89 is $2.79, and 92 is $2.99, then you can make your own midgrade by buying 2 gallons of premium to each gallon of regular. So, if you are under 1/4 of a tank, you might buy 12 gallons total of which 4 is regular and 8 is premium for a total cost of $33.96. Or you could buy 12 gallons of midgrade at $33.48. Making your own "midgrade" is what you do at stations that don't offer a midgrade at the pump.

>Tfw gas in NJ was 1.89 premium a year ago but the gas tax fucked it all up

Why are you so poor you can't afford the extra $10-20? Don't eat your shitty fast food twice every period between fueling or something.

Unless you have a tune you only need 91 coctane in the US.

Can you even pump your own gas in NJ?

Yes but you need a license.

>his premium is 92

>I don't understand differing octane rating systems

I do lol

In France they'd set police cars on fire.

>What are the main additives used to add octane level to gasoline in order to make it "premium"?

Gasoline is a mixture. It is not a uniform product. Besides the idea of "adding" with additives, things like sulfur are also subtracted from it thru refining. At some point, refining stops when the mixture is good enough to sell. It varies by manufacturer since they own different refineries and the ingredient percentages vary all the time because the crude oil sources are highly variable in content.

Thus pipeline gasoline from refineries will vary in the amount of other solvents and impurities mixed into it. Top Tier gas doesn't use MMT or Ferrocene. It has lower limits on sulfur than non-top tier gas. For Top Tier, octane is boosted by ethanol, toulene, and xylene.

Gas formulations change. Here is ARCO year 1998 gasoline:

The above data is what the company furnished to the US Government as a matter of public record.

>98 RON costs a shitload more than 95
>get better fuel economy

Probably a good idea to go with 98.

What kind of setup do you have where increasing octane increases gas milage?

The kind where better compression = more efficiency?

...

>What kind of setup do you have where increasing octane increases gas milage?
The kind of setup where stats are gathered for the EPA in making up that Estimated City Miles and Estimated Highway Miles rating bullshit for those new car window stickers.

Looks like MTBE went out when Arco accepted the Top Tier gasoline standards. Walmart/Sam's Club gasoline is one of the USA's largest gasoline sellers that sells non top tier gas. Since there is still a lot of higher sulfur (less refined) gasoline being made, it stands to reason that such cheap sour gasoline is going to the sellers such as walmart / sam's club.

It's those cars using that gas which probably need the additives the most.
